The necessity and significance of promoting spraying machines for plant protection and greening
The main function of the sprayer is in slope greening projects. Due to the extreme deterioration of the global environment, slope greening has gradually been put on the agenda. The existence of sprayers plays an incomparable and important role in slope greening projects. Next, we will discuss the necessity and significance of implementing sprayers for plant protection and greening.（1） The meaning of spraying machine greening.In the scale of "National Health Zones", it is repeatedly mentioned to "actively implement three-dimensional greening", "insert greenery into gaps", and "advocate the development of various greening forms such as roofs and verticals". In the central urban areas of large and medium-sized cities, where population is dense and green land is scarce, three-dimensional greening highlights its importance and feasibility. Ground greening refers to planting trees, flowers, and grass in the city to cover and dress up the exposed ground.（2） The deteriorating urban ecological environment requires reform.At present, the urban air quality report in China shows that more than 80% of cities are facing important air pollutants such as inhalable particulate matter (also known as suspended particulate matter). One main way to reduce the suspension of such particles in the air is to reduce the urban heat island effect and assist in urban cooling. Because this can reduce the upward heat flow of urban ground, causing particulate matter to descend and adhere to the ground, building surfaces, and vegetation. There are various methods internationally to cool down cities, which can be summarized as important: using trees for shade, allowing the ground to breathe, planting multiple layers of vegetation, climbing plants on walls, reducing energy consumption, and so on. Scientists have invented that on two streets with similar emissions but with and without trees, the suspended particulate matter in the air of the latter is ten times higher than that of the former. This indicates that trees can assist in reducing 90% of suspended particulate matter.（3） The current shortage of urban green land requires the implementation of slope greening to alleviate it.China has a large population, arable land resources and urban land are very tight, different from Europe, Australia, New Zealand, Russia, the United States, Canada and other countries and regions! In the central urban areas of China's large and medium-sized cities, most buildings are crowded, the population is dense, and green land is scarce. Slope greening is particularly important and urgent. Faced with the enormous pressure and strict challenges of urbanization, population, and environmental resources, future urban development will also reflect the characteristics of this period and can only take the path of urban ecological development. Slope greening is the exchange of space for green space, allowing greenery to move from flat surfaces to slopes, further expanding the green space of the city. It is a new direction and effective action for urban greening, saving land, opening up urban space, and greening and beautifying the city. In order to alleviate the shortage of urban green land, vigorously promoting slope greening is an urgent task for improving urban greening. Slope greening increases the urban green area. The murky air and the sound of bathing are pollution that residents in today's cities find difficult to avoid. However, by implementing slope greening and increasing the green area, all of these can be effectively improved. Germany has conducted actual tests, and the buildings on both sides of the street have been treated with slope greening, which reduces the dust on the street by 3-4 times compared to before greening. Reasonable slope greening can effectively regulate indoor temperature and humidity, reducing heat exchange between outdoor space and enclosure surfaces.（4） It is necessary to connect buildings with the environment.High rise buildings often serve as iconic landmarks in cities due to their grand scale. There is an undeniable obligation to shape the urban environment. Therefore, when applying the idea of slope greening to architectural design, sufficient consideration should be given to the overall urban environment, and the greening should be adapted to urban requirements in terms of design. Slope greening can purify the air, reduce waste heat discharge in summer, and maintain indoor temperature in winter, which has the function of reducing greenhouse effect. It also protects buildings from damage caused by high temperatures, ultraviolet rays, etc., which is beneficial for extending their lifespan. Slope greening can not only improve urban greenery, soften the rigid architectural landscape, beautify the urban environment, but also prevent dust and noise, resist pollution, cool down and prevent heatstroke, maintain vision, and so on.（5） The extension of green in three-dimensional space is necessary.In the past, skyscrapers obscured the sky, highways divided the earth, and patches of green trees were eroded. It is difficult for people to regain the tranquility of crossing forests, the relaxation of overlooking rivers, lakes, and seas, and the divine joy of facing rushing streams. Slope greening allows people to obtain a good psychological beauty, and green symbolizes vitality, making people feel a desire for life. Nowadays, slope greening can not only have a good psychological effect on the human body, providing satisfaction and comfort, and regulating people's mental health, but green plants can also resist pollution from harsh environments, absorb dust and toxic gases, and kill bacteria. Meanwhile, trees are well-known for their ability to reduce noise, absorb carbon dioxide, and release oxygen. Green plants can also block the radiation of summer sunlight, and buildings with slope greening have a room temperature 2 to 3 degrees lower than those without three-dimensional greening. From this, it can be seen that doing a good job in slope greening is of great benefit. It can regulate the human nervous system, relieve tension and fatigue, and enable impulsive people to restore quietness. In the urban complex of high-rise buildings, green will become the entry point for dialogue between people and the environment.The implementation of slope greening projects is of great significance to the ecological environment of the entire earth, so the necessity and importance of the existence of sprayers are self-evident. The five points of importance and significance mentioned in the appeal are summarized by the editor, hoping to make everyone more aware of the importance of the sprayer for slope greening projects.
